Letters Patent of the United States, Serial' No. 831,393, granted to me on September 18, 1906, and in the application for Letters Patent of the United States for an automatic button cutting and shaping machine, 'Serial No. 324,643, filed by me on July 3, 1906.l

The object of the invention is to provide a new and improved cutting and facing tool more especially designed for accurately cutting out the button from a shell and simulh taneously facing the button.

The invention consistsof novel features and arts and combinations of the same, whi'cli) will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is representedin the accompanying drawings forming a part of this specification, in which lsimilar characters of reference indicate corengaged by a self-centering chuck of any ap-` proved construction, and held on the spindle of the automatic button-cutting and shaping machine above referred to. Within the tubulartool-holder is held the tubular saw B split in the direction of its length and provided at one end with saw teeth B and a cutout portion B2, the tubular saw when'not in position in the holder A being larger in diameter on the upper end than on the end carryin the teeth B', so that in -order to insert the tu ular saw B into the holderit is necessary for the operator to press the saw on opposite sides of the spiit, reducing the diameter sufficiently to allow the'insertion of the saw into the tool holder, the saw on being released immediately expanding by its own resiliency so Specification of Letters Patent.`

as to forcibly contact with the inner surface of the holder, thus holding the saw tightly in place in the holder by its own resiliency and without further mechanical fastening devices. The saw may also be driven into the holder A after the small end is inserted in.

the holder.

Within the tubular Saw B is held tightly a filler and carrier C for stiifening the tubular saw and for carrying the facing tool D. The filler and carrier is preferably made of wood which when driven into the tubular saw and Ymoistened and expands, is held securely in the saw B by friction, and without further mechanical fastening devices. The filler and carrier C is provided with a groove C which preferably 4extends from the lower end to the upper end, and into this groove fits the facing tool D having its lower on cutting ortion projecting beyond the'lower end of t e filler and carrier'C, the lower or cutting edge of the facing tool D being within the lower'end of the tubular saw B and'opposite the cut-out portion B2, to allow the introduction of the corner of a grinding wheel for grinding the cutting edge B `whenever deemed necessary. When the tool is rotated and fed into a shell or other material E then the saw B makes a circular cut and the facing tool D cuts the faceof the material, defined by the cut, to Vgive the face of the button the desired ornamental shape. tion B2 in the tubular saw, the tubular cuttings can readily work out, thus having the tool at all times in good condition to do good work without danger of clogging.

From the foregoing it will be seen that the tubular saw B and the facing tool D are held in the holder A, and the filler'and carrier C, without the use of eXtra mechanical fastening devices, and in addition the filler and carrier C fills the tubular saw B to stiffen the same. When it is desired to. adjust the tubular saw B in the holder, or the facing tool D, it is only necessary to slightly tap the up er edge of the tubular saw B or the u )per en yof the filler and carrier C with a suitabletool, until the lower cutting edges of the saw B and the facing tool D assume the desired relation one to the other. The teeth B ofthe tubular saw B can be readily sharpened, by filing the same, and the facing tool can be readily ground by the use of a revolving grinding wheel without removing either the saw B or the facing tool D from their supporting members.A The' holder A is prefer- By having the cut-out porv Patent:

l. A tool for cutting buttons and the like, comprising a tubular tool holder, a tubular split saw held inthe tool holder by its resiliency, a filler and carrier held in the said tubular saw, and a facing tool held on the said filler and carrier.

2. A tool for cutting buttons and the like, comprising a holder, a` tubular split saw in the older, a Wooden filler and carrier fitting snugly in the saw and held therein by friction, and a 'facing tool carried by the said filler and carrier. v

3. A tool for cutting buttons and the like,

comprising a tubular saw 'having a cut-out portion at one end, and a facing tool within the said tubular saw and having its cutting edge o where grinding device by way of the said cut-out portion in the tubularsaw.

4. A tool for cutting buttons and the like, comprising a holder, a tubular split saw in the older, a filler and carrier fitting snugly in the saw and held therein by friction, said iller and carrier extending from the upper end of the saw to a oint near the vlower end thereof andl rovi ed with a' longitudinal oove exten ing 'the le th thereof, and a acing tool in the groovelcl the filler and carrier and projecting beyond the lower end of the same.

In testimony whereof yI have .signed my name tol this specification in the presence of two subscribing witnesses.
